Readahead can break our mix of aio/dio and buffered io. Although the dio path will invalidate pages before and after initiating the IO, and we do not issue racing buffered reads, the readahead code might. That would result in pages in the page cache that are not coherent with an aio write. This is easy to reproduce with ceph_test_objectstore's Synthetic case when bluestore_default_buffered_read=true.
